Subject: [PATCH] drm/i915/bxt: add missing DSI power domain to power well 1
Date: Tue, 8 Mar 2016 21:00:56 +0200 [thread overview]
Message-ID: <1457463656-29357-1-git-send-email-jani.nikula@intel.com> (raw)
The DSI power domain was missing from BXT power well 1 definitions,
failing to get the power well for DSI transcoders. As pipe A is in the
same power well as DSI transcoders, the problem should only occur with
pipes B and C.

This should superseed [1], but a change will be required in
haswell_get_pipe_config() or [2] to check the DSI power domain.
